Are lockscreens outdated?

In one of their latest shows, Vernon and Andrew from the awesome Glance and Go Radio discussed whether or not having a lockscreen still makes sense.
Unlike many people may think, lockscreens were not really meant to protect a device from being accessed by other individuals, but derived from the keypad locks cell phones used to have to avoid accidentally performing a phone call while carrying the device in your pocket (butt dialing).

While you may argue about the actual use on touch devices, I find lockscreens a great way to further personalize my device. Especially with the new features Microsoft introduced with Windows Phone 8.
Meanwhile several dozens of all kinds of lockscreen apps can be found in the Windows Phone store. Some of them offering quite unique features. I’m currently going with Lock Buster, which you can find here.

And even though there are certainly more important parts of the OS which need optimization and improvements, I seriously hope Microsoft hasn’t reached their end of the line with the lockscreen options. I personally would like to be able to add more than just 5 apps to it. I don’t see a single reason why a second array of icons couldn’t be added.
And while these icons at least serve the purpose of letting users know about the amount of new items for the configured apps, I don’t see it necessarily stop there. I’d love to be able to tap the icons to have them reveal more detailed information about what’s awaiting me. These could simply be displayed above the clock. Perhaps with a net slide or fade in effect.
That’s just my personal opinion of course.

What do you think? Would you rather get rid of this ancient feature or keep it? Share your thoughts in the comments below.
